Hi all.
I'm having a problem running an in place upgrade of SQL Server 2005 x64 Enterprise to 2008 R2 Enterprise.
When I run setup.exe and choose "upgrade", I am able to upgrade all components apart from the database engine. I am not given the option to select an instance prior to this. I have ensured that "x64" is selected from the bottom "options" tab on the initial setup screen. My current installed version of SQL is definitely 2005 x64 Enterprise, I have checked this with @@version and in the general properties of the Management Studio.
The strange thing is that if I select "x86" from the bottoms tab in SQL setup I AM able to select the 2005 instance, which lists the database engine as something it will upgrade in the next screen. Obviously I have not proceeded with the upgrade as I feel something is wrong somewhere.
Does anyone have any ideas as to how I can get the x64 install to detect the 2005 instance and upgrade the database engine?
Thanks
